Railway Tank Wagon - OS-Railway System

This Railway Tank Wagon is my second contribution to the OS-Railway system. All 3D parts can be printed without supports (otherwise there is an STL file with brim and supports included) and there is no other material needed than PLA filament for assembly.

To build this tank wagon you will need the following tools:

• Cutter
• 2mm drill
• Hot knife
• File

3D Parts List:

1 Baseplate
4 Bumper
2 Coupling
1 Frontpanel
1 Backpanel
1 Ladder Left
1 Ladder Right
1 Ladder Rungs
1 Side Panel Left
1 Side Panel Right
2 Trolly
4 Wheel

Additionally you will need straighten out 3D printer filament (1.75mm) in different length for the axes and connectors.

Steps to build the wagon:

1. Remove the brims and drill all holes with the 2mm drill.
2. Make sure the wheels fit into the cages in the trollies. If they don’t fit you can warm up the trollies with a hair dryer or a heat gun and bend the cages slightly outwards.
3. Create 2 axes out of PLA. Place the wheels in the trolly cages and push the axes through (image_01.jpg). Make sure the wheels can turn freely otherwise repeat step 2.
4. Use the hot knife to melt the endings of the axes so that they can’t slip out of the trolly anymore. (image_02.jpg)
5. Fit the coupling into the trolly. make sure they can move sideways if the train will run curved tracks. Use another piece of PLA as an axis for the couplings but also as connectors of the trolly to the baseplate. Melt the Endings with the hot knife and make sure the top is flat with the surface.

6. The side panels are sticked to the baseplate with two more PLA axes. The axes are put through the baseplate and the side panels. Use the hot knife to melt the endings. (image_04.jpg)
7. Put front and back of the tank together. You may use the hot knife to melt them together at the bottom. (image_05.jpg)
8. The tank can now be sticked to the Baseplate with two straight PLA connectors. (image_06.jpg)
9. The ladder is build out of three parts. This may be a bit tricky to stick together. Note that the “Ladder Rungs” part need a slight bend at a predefined position. (image_07.jpg)
10. Add the gangway at the top of the tank between the ladder hand rails. (image_08.jpg)
11. Assemble the front and back panels by adding the bumpers. (image_09.jpg)
12. Those parts are stuck at the front and the rear of the wagon (image_10.jpg) Finished! :-)
